Test for Solar Panel 1. Check the reading of the Open Circuit Voltage and Short Circuit Current at the back of the solar panel.

2. Clip the positive lead from the multimeter to the positive output from the solar panel, and the negative lead to the negative solar panel output.

3. Place the solar panel directly to a bright and consistent light source, such as a desk lamp

4. Turn on the multimeter and set to detect volts. The resulting value should be close to, if not exactly the same as the Open Circuit Voltage reading. As the solar panel is tilt away from the light source, the reading should drop gradually.

5. Configure the mutlimeter to read current by moving the positive lead. Turn on the multimeter and set to detect currents. The resulting value should be close to, if not exactly the same as the Short Circuit Current reading. As the solar panel is tilt away from the light source, the reading should drop gradually.
